In subsea operations, your connection to the surface is your lifeline. Whether you are operating a Remotely Operated Vehicle (ROV) for offshore inspection or a specialized underwater crawler for mining, signal loss or power failure is not an option.
Engineered by Shanghai Ruosheng Wire Cable Co. Ltd, this High-Quality PUR Subsea Umbilical Cable is designed to withstand the unforgiving conditions of the deep ocean. As a specialist in high-flexibility drag chain and special cables with over 100 diverse product varieties, Ruosheng combines robust mechanical strength with precision data transmission.
This hybrid solution integrates power conductors and fiber optics into a single, compact umbilical, reducing drag and simplifying cable management. It is the ideal choice for professionals in Europe and across the globe who require a cable that survives—and performs—where others fail.
Why Choose Ruosheng PUR Hybrid Umbilicals?
1. Uncompromising Durability (PUR Jacket)
The outer sheath is crafted from premium Polyurethane (PUR), specifically formulated for the marine environment. Unlike standard PVC, this material offers:
- Hydrolysis Resistance: Prevents water ingress and degradation over long-term submersion.
- Microbe Resistance: Protects against biological attack in varied water conditions.
- Mechanical Toughness: Exceptional resistance to abrasion, tearing, and oil, ensuring the cable survives friction against ship decks, winches, and seabed rocks.
2. Hybrid Power & Fiber Optic Design
Modern underwater robotics require high bandwidth for real-time 4K video and sensor data, alongside reliable power delivery. This cable features:
- Fiber Optics: Single-mode or Multi-mode options for lightning-fast, low-latency communication.
- Power Cores: High-conductivity copper strands designed to deliver stable voltage to thrusters and instruments.
- Shielding: Tinned copper braiding prevents electromagnetic interference (EMI), ensuring your data remains crisp even when power loads fluctuate.
3. Engineered for Motion
Static cables snap under pressure. Our umbilical is built for dynamic movement. The internal structure is pitch-optimized to handle the constant twisting, bending, and tension typical of ROV tethering and towing applications. It maintains integrity even during rapid payout or retrieval operations.

Frequently Asked Questions (FAQ)
What is the advantage of using a PUR jacket for subsea cables?
Polyurethane (PUR) is superior to standard materials like PVC or rubber for subsea use because it is mechanically tougher and chemically resistant. It withstands high pressure, saltwater corrosion, and the growth of marine microbes, significantly extending the cable’s operational lifespan in harsh underwater environments.
Can this cable be customized for specific buoyancy requirements?
Yes. Depending on your operational needs, we can engineer the cable to be negatively buoyant (sinking), neutrally buoyant (hovering), or positively buoyant (floating). We adjust the internal density and materials, often using specific foam layers or aramid fibers, to achieve the desired weight in water.
How does the hybrid fiber optic design benefit ROV operations?
A hybrid cable combines power and data in one line. The fiber optic channels provide the massive bandwidth needed for HD video feeds and sonar data that copper wires cannot handle over long distances. By integrating this with power conductors, you reduce the number of cables needed, minimizing drag and entanglement risks.
What is the minimum bend radius for this umbilical?
For dynamic applications (where the cable is moving), the minimum bend radius is typically 10-12 times the cable’s outer diameter. Following this guideline prevents internal stress on the fiber optics and copper conductors, ensuring longevity.
